sfred{ > LANGKAH : : PENYELESAIAN:}

255 – 80 = ( 2 x n ) + 25

175 = (2n) + 25

175 = 2n + 25

175 – 2n = 25

-2n = 25 – 175

-2n = -150

-2n ÷ (-2) = -150 ÷ (-2)

n = -150 ÷ (-2)

n = 150 ÷ 2

n = 75

  • 255 – 80 = ( 2 x n ) + 25

255 – 80 = ( 2n ) + 25

175 = 2n + 25

175 – 25 = 2n

150 = 2n

n = 150/2

n = 75
